Polyvalent dendrimer glocosamine conjugates prevent scar tissue formation

Article Abstract:

Dendrimers are hyper-branched macromolecules that can be chemically synthesized to have precise structural characteristics. Anionic, polymidoamine, generation 3.5 dendrimers are used to make novel water soluble conjugates of D(+)- glocosamine and D(+)-glocosamine 6-sulfate with immuno-modultory and antiangiogenic properties respectively.

Efficient preparation of organic substrate-RNA conjugates via in vitro transcription

Article Abstract:

A concise synthetic way is developed for the preparation of guanosine monophosphate derivatives carrying a decaethylene glycol spacer at their 5'-oxygen to which are attached a range of organic substrates. The results show that the more hydrophobic the guanosine monophosphate derivative is, the higher is its enzymatic incorporation.
